ANTIFREEZING VALVE.

To @ZZ whom t may concern.'

Be it known that I, JOHN H. Quinn, a

citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Antifreezing Valves, of which the following is a specification.

This invention relates vto valves for socalled hopper7 closets of the kind constructed so that the water remaining in the casing of the valve and in the pipe which leadsl therefrom to the closet will drain off when the flow through the valve is stopped thereby to prevent freezingk taking place within said casing and the pipe.

The principal object of the invention is to provide a valve of possess all of the following desirable quali ties, to wit, simplicity, strength, durability and compactness of construction, efficiency and reliability in operation. adaptability for use reversiblv. and capability of perfectly draining itself when the water is out oil'.

In the accompanying drawings, in which the invention is fully illustrated,

Figure 1 is a front elevation, partly in section in a vertical plane substantially central of the three passages of the valve casine;

Fig. 2 is a plan, moved;

Fig. 3 is a view mainly in transverse central vertical section;

. Fig. 4 shows the valve-body and its operating spindle partly in section and partly in elevation; and

Fig. 5 shows these parts in plan, disconnected from each other.

The casing a of the valve is formed with a suitable base or standard ZJ and it has a central chamber c with which communicate three passages, d, e and f, the passagesv d and e being horizontal and alined with each other and the passage f vertical; said passages are formed in three corresponding arms CZ, e and f of the casing, and these are externally threaded, as shown, for the reception of the unions d, e and f whereby the couplings g, h and i, threaded at their outer ends for the attachment thereto of the supply, waste and outlet pipes (not shown) in the usual manner and shaped preferably at their inner ends to produce ground joints g', k and z with the pasthe couplings being `rethis type which shall Specification of Letters Patent.

Application filed August 12, 1916. Serial No. 114,499.

saged arms rZ, e', and f, are connected with said arms. V I

At cl" and 6 the passaged arms CZ and e are reduced so as to form both a bearing and a seat in each instance for the valve (to be described), leaving an enlargement to form a valve chamber between each such bearing and seat CZ (6W) and the adjoining coupling` g (h) the valvel chambers are designated 03 (e).

In the bearings im and efv is guided t0 moverectilinearly and without 'transverse play the said valve. This is shown best in Figs. 4 and 5 and consists of the cylindrical body y' iuted or channeled longitudinally, except at its eXtreme ends, and having its said ends recessed as seen best in Fig. 4, and Fuller or equivalent washers or valves proper 7c litted thereto and secured in place by screws or the like Z, having play in the valve chambers elm', 6. Movement of the valve ,rectilinearly brings one or the other of its washers against a seat cZ, e Y

the supply pipe, as the requirements of the application ofthe device in the plumbing may demand; and in either case the pressure of the supply normally tends to seattlie valve so as to stop the flow fro-m the supply. For operating the valve proper I provide the spindle m having an enlargement n at one end formed with an 'offset arm n', making the spindle in eifectfa crank; the other end of the spindle or crank is squared and adapted to receive a lever, preferably weighted, vdesignated 0, to which an operating` wire or chain p may be attached. The arm 'n' is received by a cross-cut recess g formed vertically in the body I7' of the valve. The bottoml of the recess and the outer face of the arm n are flat and bea]l squarely against each other, and since the arm reaches below the central horizontal plane of the valve'in contact with the bottom of its recess the valve is prevented by the 'crank from turning in its bearing in the valve casing.

To afford a substantial bearing for the crank m and permit the Same to be readily assembled with and detached from the other parts, l screw into the threaded hole r formed in the back of the casing a so as to enter its central chamber c substantially cens tral thereof a bushing s, whichmay have screwed onto its outer end a stuflingbox or gland containing'packing u.

In the normal position of the moving parts, the valve closes oft' the supply of water, which in the present instance is assumed to be admitted through coupling g, the weighted lever 0 and the water pressure holding the right-hand "Washer 71; seated. Vhen the lever is raised the valve will be shifted to the right, unseating the righthand and seating the left-hand Washer 7c, so that the water passes through the central chamber c and out through coupling f`towardjthe closet. On the lever being allowed to fall, the valve is `returned to .its normal position, seating the right-hand and unseatl ing the left-hand washer 71;, so that the water is againy cut ofi", and such water as re- 'mains in the valve casing a and the voutlet vpipe connected to coupling z' drains V01T Lthrough coupling h, leaving themV entirely free of water.

To prevent the washers from being subvjected to undue pressure when the valve yproper is-moved to either of its limits the Varm 'np the crank, asit pushes against one side of ythe slot Q, is adapted ultimately to impinge 'against the other side at the corner o.

It'will'beapparent that my construction not only produces a valve structureY that is perfectly self-draining in character, but that, 'chiefly due tothe straiglittlirough ar- ,rangement `of the supply and waste ypassages, lwith the outlet passage arranged to bisect their'line midway between them, the deviceV may be made symmetrical-in form fand kreversible and Vmay be? produced with "theminimum of vWorking parts and Ywithr certain'assurance that they will operate'to best advantage. Y

'Having thus fully described *my Ninventiomfwhat' If-iclaim'and desire `to securev by "Lettersy Patent is:

1. "'In'combination, a casing having a central chamber, alined supply and waste passages communieating` with said chamber at opposite sides thereof and an outlet passage also communicating with said chamber be` tween the points of communication `therewith of the supply and waste passages, said supply and waste passages each having a relatively inward reduced portion c and a relatively outward enlargement forming a valvechamber, a valve movable back and forth in and longitudinally of said supply and waste passages and including .a yfluted cylindrical valve body snugly fitting said reduced portions and two valves proper -respectivelyarranged :in said valve chambers 'and adapted to alternately seat relatively .snugly iittingeaeh passage and two valves proper, one for each passage, on said body, a bearing-bushing s removablyA arranged yin said casing 'with the bearingv axisv thereof penetratingvsaid chamber'and at rightangles to the-line of reciprocating-movement of the valve, said -va'lve having a krecess therein laterally yopen toward the bushing, and an operating crank journaled inthe. 'bushing `with its axis concentricwith'the axis of the bushing and having an arm within saidchamber and arranged in said recess,V the bottom of the recess beingeflat and the crank arm' having al fiat face perpen dicular to thelalXis of movement Of'thecrank and bearing flat against said bottom ofitherecess.
